Colorado Potato Beetle Control with Transplant Drench Treatments of Admire to Bedding Trays of Tomato and Eggplant, 1995

The experimental design was a split-split plot with eight randomized blocks in which two host crops (tomato and eggplant) were designated as whole plots, seven imidacloprid doses as sub-plots, and two times of application (one day and 7 days before transplanting) as sub-sub plots. Drenching doses were 0, 0.25, 0.5, 1.0, 2.0, 4.0 and 8.0 ounces of Admire 2F per acre equivalence of bedding trays of tomatoes and 0, 0.18, 0.38, 0.75, 1.5, 3.0 and 6.0 ounces of Admire 2F per acre equivalence of bedding trays of eggplant. The diluted drench was applied to individual cells of bedding trays using a pipetted volume of one ml per plant. Plot size for each treatment combination was one row 20 feet long (20 tomato plants, 8 eggplants) with rows spaced 72 inches apart. Plots were planted 9 Jun using 288 cell trays. After transplanting, weekly counts were made of live and dead adults, percent defoliation, and percent stand loss.
